3. A) Show all the unique mono-halogenated products for the reaction below. Circle the major product. Br₂ light B) Show the formal arrow pushing mechanism for the first and second propagation step which leads to the radical intermediate of the major product. Be sure to draw in the hydrogen which is being abstracted. Draw the products.

6. Consider the following reaction: CH3 HBr. ? ČH3 a) Draw the two possible allylic cations that could be produced as an intermediate in this addition reaction; include resonance structures. b) Which of these allylic cations is more stable, explain briefly how you arrived at that conclusion? c) Draw the complete mechanism for the addition reaction involving the more stable allylic cation intermediate showing the formation of both the 1,2 and 1,4 addition products, include arrows, formal charges and electron pairs. d) If the reaction is carried out at 0°C, what would be the major product? e) The reaction is then carried out at 80°C, and the major product was found to be the same as when the reaction was carried out at 0°C. What is the kinetic product and what is the thermodynamic product? f) Assuming the first step is rate determining, and the reaction is spontaneous, sketch a reaction coordinate (energy diagram) for the mechanism drawn in part c). Label the reactants, products (kinetic…

3. Reaction mechanisms! For each reaction in the multistep synthesis below, draw the arrow- pushing mechanism (unless noted). Make certain to draw the structure of the product of each reaction. For any radical mechanisms, you do NOT need to draw any initiation or termination steps – simply assume the formation of the radical which carries the chain reaction, and draw each propagation step in the mechanism. For EAS reactions, please DO draw the mechanism of the formation of the electrophile from the reactants, including the structure of the electrophile which actually attacks the ring. Continue onto a second page if necessary. 1. `CI • AICI3 2. HNO3, H2SO4 3. Zn/Hg, HCl (Clemmensen reduction -- no mech required) 4. Br2, heat/light 5. NaOEt, EtOH, heat 6. Br2, H2O

I need help making the mehanism for the reaction with Hbr and this compound.   Then sketching an energy diagram that shows rate dermining, reactants, products (kinetic and thermodynmic) and intermediates.
